Glossy varnish is transparent coating that made up of base materials and additives, and do not contain any pigments, used in the surface treatment of packaging materials.
- Used in the printing industry
- Influences ink color, curing speed, layer thickness, and weather resistance
- Reactive diluent reduces viscosity and disperses pigments
- Determines external characteristics such as viscosity, hardness, and flexibility
- Provides a glossy finish
Varnish is one type of synthetic resins that is commonly used in the surface treatment of various materials. The transparent coating is made up of base materials and additives, and do not contain any pigments. Once applied and dried, they provide a glossy finish that is commonly known as clear varnish.
Varnish is primarily used in the printing industry, where it can significantly impact the color of ink, its curing speed, ink layer thickness, and other properties such as weather resistance. The reactivity of the varnishing's diluent is a crucial factor in determining the viscosity and hardness of the ink, as well as its flexibility and other external characteristics.
The varnish reactive diluent is a small-molecule chemical that can reduce the viscosity of the ink and disperse pigments. As a result, it plays a vital role in determining the ink's external appearance, such as its viscosity, hardness, and flexibility.
Different surface treatment methods can protect and showcase various packaging effects. Glossy varnish is one kind of synthetic resins that is commonly used for surface treatment, primarily used in the printing industry, providing a glossy finish that enhances the visual appeal of the treated surfaces.
